Overview
A fuse-box hardwire kit for a specific set of Uniden radar detectors, wiring the unit directly into the fuse panel with a remote mute and mark button, freeing the 12 volt socket for other devices.
The value here is less about performance and more about installation: a fixed wire connection instead of a cord to the cigarette lighter, plus a small remote panel with its own mute button and status LEDs mounted where the driver can actually reach it. It only works with the Uniden models listed, so checking that list matters more than any other spec.
- Direct-wires into the vehicle's fuse panel
- Remote mute and mark button
- Separate power and radar/laser alert LEDs
- Compatible with 11 named Uniden detector models
Who it's for
Fits owners of a listed Uniden detector, R8, R8W, R7, R4, R4W, R3, R1, DFR9, DFR9BLK, DFR8, DFR7 or DFR6, who want a cleaner, permanent install and a free 12 volt socket. It will not work with other detector brands or with Uniden models outside that list.
Strengths and trade-offs
Drawn from this product's published specifications.
- Frees the 12 volt socket for other devices
- Remote mute button mounts within easy reach
- No battery required once hardwired
- Separate LEDs show power and alert status
- Works only with the listed Uniden models
- Installation means wiring into the fuse box
- Adds a separate small control box to mount
Performance notes
A T-Tap connector taps power from the vehicle's fuse panel, so the detector runs without a cigarette lighter cord or its own battery. The small remote box carries separate power and alert LEDs plus the mute/mark button, so status and radar or laser alerts are visible without looking at the detector itself. On GPS models, a double press activates mute memory.
